IGNITION TIMER.

Application led Iovember'6,r1922, Serial N o. 599,238. Renewed February3,1927.

This invention relates to ignitionvapparatus for internal-combustionengines, and more particularly to the timer and distributor unitcommonly called the distributor.

one of a set of interchangeable parts suchl as sets of timer cams,distributor rotors and distributor heads, whereby the distributor lllcan be adapted for either direction of rotation of its driving shaft,and can be adapted to provide ignition for engines having differentnumbers of cylinders, for example, 4, 6 or 8 cylinders. In this mannerthenumber of different parts required for producing apparatus fordifferent engine requirements will be reduced to the minimum.

A further object is to provide a distributor in which the internalelectrical circuits are provided without the use of wire oonf ductors.

' A further object is" to provide means for manually adjusting thedistributor, said means cooperating with any one of a series of manualtiming range stops each of lwhich permits the proper range of manualadjustment for the particular engine with which the distributor is' tobe used.

Further objects and advantages of theA present 'invention will beapparent from the following description, reference -being had to theaccompanying drawings, where a pre- Aferred embodiment of the present'invention is clearly shown.

20 designates a timer cup which has acylindrical shank 21 and an annularflange 22 concentric with saidl shank. Shank 21 is centrally aperturedtoreceive a bushing 23 which provides a bearing :for the main shaft viewof the distributor Fig. 14 is a plan view of the distributorv I' .24.Shaft 24 carries` at its lower end a coupling 25 having tongues 26adapted to beengaged by notches in asimilar memberl the vweightleverrests upon one 'or two hut tons 31 whichare struck up fromthe up persurface of the weight base. This construction tends td reduce frictionwhich would retard the movement of a weight 1ever 29 about its pivot 28.Each weight is provided with a finger 32 which enga an.

di? a.

arm 33 of'the automatic cam or sp1 Spider 34 is attached to the lowerend of cam shaft 35 which is journalled upon the reduced upper end 36 ofthe driving shaft 24. (See Fig. 11). The lower end of shaft 35 is spacedfrom the shoulder 37 of the shaft 24 by means of a washer 38. Two spiderarms 33 each carry a spring post 39, and' 'ignition timer as thespeedincreases as will be apparent more clearly hereinafter. The lowerend of post 39a extending into hole 27* cooperates with plate 27 toprovide a stop limiting the movement of the weights 29. In the innermostposition of the weights 29 the`A springs 40 extend radially and the post39* practically touches one side of the hole 27a. It is apparent thatthe governor is constructed for a timer in which the timer cam shaft isto revolve in a counterclockwise direction.

If`it is desired to adapt the apparatus for an installation in which thetimer shaft ,is revolved in a clockwise direction, the weights 29 arereversed upon their posts 28 as shown at 29a in Fig. 16F and have theweight plates 30 welded on the opposite side from that shown in Fig. 10,whereby lthese weights with their' plates are arranged forcounterclockwise rotation outwardly upon their weight posts. Thereforein such a construction when the`weights swing out the spider 34 will berotated clockwise relative to the shaft 24, and will advance the timercam shaft 35 in a clockwise direction as viewed in Fig. 16. It is alsonecessary to interchange the post 39* with a post 39 so that the post39a in its new location will extend into a hole 27 b in plate 27. Whenthe automatic mechanism is at rest, the post 39a in Fig. 16 willpractically touch one side of the hole 27". Therefore hole 27" servesthe same purpose as the hole 27"l does when the apparatus is arrangedfor counterclockwise rotation.

The timer cam shaft 35 is prvided with a tapered portion 41 and areduced'upper end which is threaded at 42-to receive a nut 43. (See Fig.11). The timer cam 44 is centrally apertured to receive the taperedportion 41 and the reduced portion 42, the

cam having conical portions 45 and 4'6 which bear against the taperedconical portion 41 of the shaft 35. After the cam 44 has been located inproper position of adjustment ing a flat portion 51 conforming to thelflat 75' 48. This construction provides for locating the distributorrotor in proper relation to the lcam 44. The rotor 49 supports a segment52 which is riveted at 534to a preferably metallic member 54, or insertaround which the distributor rotor is molded. A felt wick or plug 35aacts as a lubricant reservoir to supply lubrication between parts 35 and36.

The cam 44 as shown in Fig. 2 will pro- 85 vide ignition for Aa'sixcylinder four stroke cycle engine. In order to accommodate thedistributor to a four or eight cylinder engine, it will be necessaryamong other things to substitute for the cam 44 other cams hav- 90 ingfour or eight lobes, for example, to suit the requirements of a four oreight cylinder engine.

The flange 22 of timer cup 2O supports a circuit breaker base 60, saidhase being held .down by screws 61.

The base 60 is provided with metal bosses 62, 63, and 64 preferably inarcuate alignment with 'a central aperture 65 surrounded by a boss 66,and

with two elongated openings 6 7 and 68 pref- 100 erably th/e samedistance from the hole 65 and concentric therewith. (See Fig. 12). Thebase 6() is provided with a counter-bored` recess 69 in alignment withthe elongated hole 67 and this recess is adapted to receive 105 one of aset of interchangeable washers 70 having the same external diameter butvarying in internal diameter for a purpose to be described.

The circuit breaker plate 71 is provided 110 with a central apertureadapted to receive the boss A66 which serves as a bearing for the' plate71. In order to yieldingly maintain the plate 71 in engagement with thebosses 62, 63 and 64, andthe base 60, the plate 71 115 is provided withhold-down studs 72 which extend from the plate 71 down through thearcuate slots 67 and 68, and each of these studs is reduced at its lowerend to provide a threaded portion for engagement by a nut 73. Thereducing of the lower end of the Stud in diameter provides the stud witha stop shoulder 74 which definitely limits thc distance to which the nut73 can be screwed along the stud 72. Between the nut 73 and 125 theunderside of the base 60, the stud 72 is surrounded by a plain washer 75and a spring washer 76. The' plain washer 75 is yieldingly pressed bytheSpring washer 76 against the lower face of the circuit breaker (See Fig.15). 70

l this manner the plate 71 will be maintained substantially at rightangles to the cam shaft and there will be little tendency for the plateto get loose and rattle. O11 the other hand `this plate is relativelyfree to turn about the central boss 66.

A terminal bracket 80 is attachedito the plate 71'but insulatedtherefrom, there being a non-conducting member 81 between the bracket 80and the plate 71, and a non-con ducting strip 82 is located on top ofbracket 80 to receive the heads of rivets 83 the Shanks of which areinsulated from the bracket 80 by means of non-conducting washers 84located within holes 85 and having sufficient internal diameter toreceive Bracket 80 1s` the Shanks of the rivets 83. provided withfacondenser supporting ear 86 having a plain aperture 87 and with acontact supporting ear 88 having a threaded aperture 89. Bracket 80 isprovided with a -threaded aperture 90 for receiving the terminal screw91, the lower end ot which extends through an enlarged'hole 92 providedin the handle portion 93 of the breaker plate 71. .The handle 93 isprovided with a hole 94 gr receiving a link or the like by which thebreaker plate 71 may be rotated from a distance as by means of the usualspark vance lever on the steering post of an automobile. It will beclear that when the circuit breaker plate 71 with all the parts mountedthereon as explained in detail in the following paragraph, is manuallyrotated about the bossy 66 by the handle 93 the spark will be advancedor retarded according to the direction of rotation of said plate 71. Thearcuate slots 67 and 68 in the base 60 thr Uh which the hold down studs72 extend permits the rotation of plate 71 through a range depending onthe length of said arcuate slots. A set of interchangeable washers 70(described above and clearly illustrated in F ig. 12) is provided forchanging the length of the arcuate slot 67 and thus for provid theproper range of manual adjustment o1 the spark for the particular enginewith which the distributor is to be used.

The handle 93 of the breaker lever plate 71, the terminal bracket 80 andthe non-conducting plate 81 extend through a notch 931l in the flange orside wall of the base or container 60, thel notch 93a being 'slightlydeeper than the combined thickness of these parts. The part 82 extendsabove the plane of the lower edge of the\ distributor head 150 which isseated u A n the flange 60?. The parts 71, 80,81 an 82 have cylindrialedge surfaces' indicated at 71, 80, 81* and 82a respectivelyl in Figs.5, 3'and2. These cylindrical surfacesl combine to provide a closure forthe notch 93* in all positions of -bes metallic condenser can 134whichuis V over t 135 against a metallic button 136 which 1selectrically connected with 'the the lever 93, and thus tend to prevententrance of dust and other foreign matter within the timer housingprovided by the base 60 and the head 150. ,Y

A threaded rod 100,'carrying a nut `101 andl a contact 102 and having ahexagonal head 103, has threaded engagement with the hole 89 in ear 88.By turning the hexagonal head 103, the rod 100 may be screwed in and.out with respect to the ear 88 for purpose of adustment and the rod 100is secured in a just/ed position by means ot' the lock nut 101. rlhecontact 102 is adapted to be engaged by contact 104 riveted to an ear105 substantially at right angles to the main portion of a breaker lever106 which is locatedsubstantiallyparallel tothe plate 71. The lever 106is attached to a shaft 107 perpendicular to plate 71 having a portionwhich rests upon a circuit breaker lever hearing 108 carried by plate 71and having a portlon 109 which is journalled within the bearing 108.'llhe lever 106 carries an intermediate portion which is ben't down asindicated at 110 below the plane or the main portion of the lever andsubstantially perpendicular thereto and this portion 110 is bentsubstantially at right angles to the ear 105 as indicated at 111 andinwardly toward the timer cam da A cam rubbing block 112, preferablymicarta specially treated, is attached by rivets113 to the portion 111.The circuit breaker lever, spring 115 is coiled around the parts 107 and108 and has one end 116 pressing against the lever 106 and the other end117 pressing against a spring retainer-stud 118 which is carried by theplate 71. Stud 118 supports a condenser supporting arm 119 having aslotted hole 120 for receiving the threaded portion of a screw 121. Stud118 also supports al circuit breaker lever retainer 122 which is helddown by the screw 121 there being a lock washer 123 located between thehead of screw 121 andthe condenser "support 119. The retainer 122 hasits free end 123 dished out as shown in Fig. 6 to lit over-the riveted vend 124 ot' the hub 107 or the lever 106. By loosening screw 121thepretainer 122 may to one side to permit removal of the brea er lever106 from the base 71 for i replacement or' repairs. v

The condenserdesignated as a whole by numeral is one which is preferablyin accordance with the invention disclosed in the copending applicationof August Toelle,

132 and attached to but insulated from a condenser end cover 133 whichis soldered to a spun 1 othercondenser foil. /IIhe button 136 carries pa stud 137 having al threaded portion 138 passing through the condensersupport 119 and receiving a lock washer 139 and a nut 140. The screw 132passes through the hole 87 in the ear 86 of bracket 80 and attaches thecondenser core 131 mechanically and electrically to the bracket ear 86.A lock washer 142 is located between the head of screw 132 and the ear86 which is positioned against the protruding end of the core 131.

The distributor head 150 made of molded nonconducting material such asbakelite embodies certain features disclosed in the patent to O. F.Conklin No. 1,372,065, issued March 22, 1921. The head 150 is provided.with a circular row of high tension cable receiving sleeves 151disposed concentrically about a central cable receiving sleeve 1 52.Sleeves 151 are provided with metallic lining members 153 and needles154 extend centrally of the lining members 153 and are attached toinserts 155, preferably of Monel metal which has been embedded in thebakelite of the head by molding the bakelite around the inserts. Thecable receiving sleeve 152 is provided with a metallic lining 156 intowhich projects a needle 157 attachedL toa sleeve 158 within which slidesa button 159 yieldingly maintained in engagement with the distributorsegment 52 by means of a spring 160. The sleeve 152 receives the hightension cable from the secondary windl ing of the ignition coil, needle157 enters in between the strands `of the cable and provides aconducting path to the distributor segment 52 which distributes sparkingimpulses to the distributor posts or inserts 155 in recurrent sequence.Each of the needles 154 enters between the strands of a high tensioncable received `by!- the sleeve 151, said. cable being attached tol'anengine spark plug. The distributor head 150 is held down upon thelcircuit breakerbase 60 by means of spring clips 161 each having a hookrtiony 162 received by a recess 163 provi ed in the base 60. -The fiange22 of the timer cup will close the lower end of this recessv163-when thebase 60 is attached to the cup 22'as shown in Fig. 9 and therefore thehook end 162 will be retained within-this recess. The clip 161 isprovided with a loop 164 adjacent its upper end adapted to be receivedby a socket 165 provided by the head 150, and this loop 164`is adaptedto snap over a shoulder 166' which prevents accidental displacement ofthe clip 161."v The connection between the hook end 162 and the recess163 is loose enough to permit swinging the clip 161 away from rthe head150. so that the head can be' removed froml the base 60. The head 150carries a lug 150* adapted to fit between the sides 172 and 173 of anotch 174 for the purpose of locating the headonthe'baseO. 4

Lubrication for the shaft 24 is provided by means of a grease or oil cup170 communicating through passage 171 withthe shaft 24.

The ignition apparatus'described is adapted Jfor use in a groundedsystem of ignition in which the engine frame which supports the ignition.timer serves as a part of the primary ignition circuit. In such systemsit is customary to ground one terminal of the battery and to connect theother terminal with .an ignition switch which in turn is connected withone primary terminal of the ignition coil. The other primary terminal ofthe coil is connected in any suitable manner with the terminal screw'91. The high tension terminal of the ignition coil is connected by asuitable cable with the sleeve 152 and needle 157 and the otherdistributor posts are connected by suitable cables with vthe spark plugsof the engine. There arey no wire connectors located within thedistributor` The terminal bracket 80 serves as a conductor to thestationary contact 102 and to one terminal of the condenser. 130. Themovable contact 104 is grounded through 'the breaker lever 106 and plate71. The other terminal of the condenser 130 is grounded through itssupporting member 119. The retainer 122 also serves to ground thebreaker lever 106.

Where the timer cam normall rotates counter-clockwise as viewed in Flg.2, the

This new location of the cam relative to the automat-ic mechanism isindicated at 444. The same piece is used, therefore the flat will 'be inthe position 48a. The cams 44 and 44B shown in Figs. 15 and 16,respectively are ust touching the circuit breaker block 112.

urther movement of cam 44 counterclockwise will cause t-he breakercontacts 102 and 104 to separate to cause sparking, andv furthermovement 'of'cam 44 clockwise will 4clause the contacts 102 and 104 toseparate.

It is apparent' that automatic' advance mechanism and the timer cam havebeen' arranged for clockwise rotation without adding 4or substitutingany new parts. The parts shown in Fig. 15 and preceding figures havebeen rearranged. In order to provide for distribution of the sparkingimpulses two rotors are used, Arotor 49 (Fig. 14) for counterclockwiserotation and rotor 49 (Fig.

117) for clockwise rotation (as viewed in Fig. 1'6). These rotors differonly in respect to the location of their flatsJ 51 and 51?,respectively, to their rotor segment 52;, A normal line to the fiat 51(meaning aline passing through the axis ,of the rotor and perpendicularto the flat 51) is located below the center line of the rotor segment asviewed from one direction of rotation to the opposite. For example, ifthe cam 44 is rotated 40 degrees to bring it 'from the position shown inFig. 15 to position 44 in Fig. 16, then the angle between the normal to,the locating fiat in the rotor recess to the center line or the rotorsegment will be 20 degrees.

To accommodate the distributors in engines having a number of cylindersother than sin, it is obvious that the distributor head and the timercam must be replaced by corresponding parts which are constructed tomeet the particular ignition requirements, In other words, if thedistributor is to be adapted ior a four cylinder engine, the cam 24 mustbe replaced by a tour lobe cam and the distributor head replaced by onehaving four i of sin equidistant sleeves 151 and posts 1,55.
